After that click on send and receive. You should start getting your messages. I’ve heard some people saying that they had to restart Evolution for it to start working (also complaints that IMAP on Evolution is really slow).

You will see the folders added to the left pane of your Evolution inbox.

2011 here and I just installed openSUSE 12.1 and using Evolution for the first time and your guide still works. The only difference I made was to pick "IMAP+" instead of plain "IMAP" and I did that because other site suggested it *shrugs* but you had the gritty details missing from that other site so thanks again!
